Aksai Had heard a lot about the Elysium Auction House during his brief interactions with the city's inhabitants.
It was said to be the place where rare and valuable items were auctioned off to the highest bidder. Of course, most of these items were acquired from the 3rd order cave.
It was likely only those who didn't like revealing their identities and yet wanted to get the best price for their valuable item would opt for selling something through auction houses. After all, the auction houses received their fair share of commission from the sellers and sometimes even from buyers as well.
Emerald Cove was earning good profits. Aksai also had also sold out many of his precious resources he cultivated inside the Everwood farm to random buyers, which had earned him loads of Spirit stones. Given his recent acquisitions and the items he was hoping to find, it seemed like the perfect opportunity.
